Two photos · One instruction · A single frame in seconds

AI Picture Merger

Cutting one person out and pasting them beside another has never fooled anyone — the light gives it away in half a second. This rebuilds both photos into a single scene instead: one window, one shadow direction, one grain.

Two rooms, two lightings, one photograph

Our own run on this site's engines. The two sources are deliberately mismatched — warm wall and hard side light on the left, cool grey and flat overhead on the right. Check her freckles and his beard survived before you judge the lighting. Every output is AI-generated.

What merging two pictures actually requires

Not a paste. The model has to read both photographs, decide what a single camera in a single room would have recorded, and rebuild the whole frame to that standard.

Image tool

Photo editors have offered a lasso and a layer stack for thirty years, and the results still read as fake to anyone glancing at them. The reason is that the hard part was never the cutting out — it is that two photographs carry two different physics. Different key direction, different colour temperature, different lens compression, different noise.

Paste one into the other and every one of those mismatches survives, which is why the eye catches it instantly even when the outline is perfect.

Our own run is the pair above, and the two sources were chosen to be awkward on purpose. She was shot against a warm-white wall with hard window light coming from her left; he was shot against cool grey under flat overhead light. Neither could be dropped into the other's frame. The output puts them in one living room under one window: her freckles and dark curls intact, his trimmed grey beard and pale blue shirt intact, a single shadow direction across both. Drag the divider and look at the two backgrounds first, then at whether either face changed.

Two honest limits. The room is invented — the model builds a plausible place rather than preserving either original background, so if the setting matters, describe it. And this is a rebuild, not a paste: at full zoom you are looking at a new photograph of both people, not their original pixels. If what you want is one picture repaired rather than two combined, old photo restoration is the other job.

How the merge runs

Upload both photos, say who stands where, compare the result against the sources at full size.

Two photos
Light, colour, grain
One frame

Similar framing merges best

Two waist-up shots combine far more easily than a full-length and a tight head-and-shoulders — the model has less scale to invent.

Name who is who

Describing each person by their clothing keeps the model from confusing which face belongs to which side of the frame.

How to use

Three steps to a frame that holds

Most of the quality is decided before the model runs, by which two photos you pick.

1

Pick two photos with similar framing

Two waist-up shots, or two head-and-shoulders. Combining a full-length with a tight crop forces the model to guess how big one person is relative to the other, and scale is the mistake nobody forgives.

2

Say who stands where, by their clothes

"The woman in the mustard cardigan on the left, the man in the navy jacket on the right." Naming them by wardrobe rather than by position alone is what stops the two faces getting swapped between sides.

3

Check the faces before you check the lighting

The lighting is almost always convincing — that is the part the model is good at. Identity is where a merge quietly fails. Put the result beside both sources at full size and confirm you would still recognise each person.

Who it's for

Why people put two photos together

Four briefs, and most of them are about someone who was not in the room.

Family

The person who missed the photo

Someone was working, someone was abroad, someone was holding the camera. A group shot with the missing person actually in it is the most common reason anyone looks for this at all.

Memory

The relative who is gone

A grandparent and a grandchild who never overlapped. It is a picture that could not have been taken, and for a lot of families that is exactly the point of taking it.

Commerce

The product and the place

A packshot on white and an empty interior become one photograph of the thing in a room. Same discipline as [cleaning up a product shot](/image/ai-product-photo-editor), one step further on.

Personal

The long-distance pair

Two selfies from two cities, one frame that looks like an afternoon together. The lighting match is what decides whether it reads as sweet or as a bad collage.

Merging FAQ

What people check before trusting a combined photograph.

Two. That is what the generator on this page takes, and it is also the case that behaves most predictably — the more people the model has to place, scale and relight against each other, the more likely one of them drifts. Merge two, then merge the result with a third if you need more.

That is the thing to check every time, and it is why the demo above asks you to look at her freckles and his beard rather than at the lighting. A merge that returns two convincing strangers has failed at the only job that mattered. If a face drifts, name that person's features explicitly in the prompt and rerun.

Because neither original background can hold both people — one was shot against a warm wall, the other against cool grey. Rather than pick a winner and relight the other person badly, the model builds one room that suits them both. Describe the setting you want if it matters.

Yes, and it is one of the most common reasons people come here. The catch is film grain and colour: a 1970s print and a phone photo carry very different textures, and unifying them means one of the two moves further from how it originally looked. Usually the older photo is the one that changes most.

No. A face swap puts one person's face onto another person's body in a single photo. This keeps both people whole and builds a frame that contains them both — different job, different failure modes. If you want two people in one shot rather than one identity on another, this is the page.

What each model costs in credits

You're only charged for successful generations. The exact estimate in the generator varies by model, length, resolution, audio, and number of images.

TypeModelCredit cost
VideoSeedance 2.5The long-take tier, priced per second: 5s 480p ≈ 211 credits, 5s 720p ≈ 473. A full 30s take runs ≈ 1,260 at 480p and ≈ 2,835 at 720p. Supplying a reference clip lowers the per-second rate.
VideoSeedance 2.05s 720p image-to-video ≈ 188 credits; text-to-video ≈ 308 credits. Scales with resolution and length.
VideoSeedance 2 FastFaster and lower cost. 5s 720p text-to-video ≈ 248 credits.
VideoSeedance 2 MiniThe cheapest Seedance tier. 5s 720p ≈ 154 credits, 5s 480p ≈ 72 credits.
VideoSeedance 1.5 ProAudio doubles the rate. 5s 720p ≈ 27 credits silent, ≈ 53 with audio; 1080p ≈ 57 and ≈ 113.
VideoVeo 3.1Billed per video, not per second (Lite tier). About 45 credits at 720p and 53 at 1080p.
VideoKling 3.0Audio raises the rate. 5s 720p ≈ 105 credits silent, ≈ 150 with audio; 1080p ≈ 135 and ≈ 203.
VideoMiniMax H3Fixed 2K, no resolution ladder. Priced per second — a 5s clip ≈ 158 credits.

ImageNano Banana ProConsistent run times across generations. 30 credits per 1K or 2K image, 50 at 4K.
ImageNano Banana 2 LiteFaster, simpler variant, and the everyday editing price: a flat 8 credits per image at every resolution.
ImageGPT Image 2The lowest-cost premium image model here. 10 credits per 1K image, 15 at 2K, 30 at 4K.
ImageSeedream 5.0 LiteFlat pricing — 20 credits per image whether you generate or edit.
